. The object of the inventionv is to-simplify-the construction of such booths, in'creasingthe rigidity'of their construction and decreasingthe inanuiacturing cost. y

In accordance with this invention, metallic booth construction is provid-edinwhich tour corner` posts are formed by bending laterallyv at a number Vci points relatively thinv metallic sheets, two of the Vcorner posts VIforming geometrical ngures of substantially square cross section while `the other Atwo corner posts are formed withngeo-I metrical `figures of substantially U-shaped cross section combined with angular `portions Aand semi-circular portions disposed to form the entrance `of the booth.

Means in the form of metallic plates secured to ltlflecorner posts along their longitudinal 'edges hold such corner posts in spaced-relation toeach other, the metallic plates extending from the top fdisposedencl-of the corner-posts-downtosubstantially one-ninth the height of 'the `bootlfiirom the surface of the floor on which the' booth may rest to form Vthe outer side wallsfand theou-ter rear wall of the booth. Means for-med fat'the -lower ends of the 4outer disposed sidewal'l'plates and the rear wall plate form ledges whichffare secured `at their -ends as vby weld-ing to thecorner posts `for reenforcing the booth structure peripherally at that level and for supporting metal-lic 'Cover-like sections"fiorini-ng the inner `disposed rear "and side wallsioi the booth. 'The innerfdisel posed metallic cover-like sections cooperate with the common outer disposedV wall plates to form therewith, at the lower ends Iof tlielattenfoasings for housing sheets-'of non-metallic `material as cardboard serving as filler therebetween,V while 'the cover-like sections at the top of the booth and "which are made ofperforated metallic plates, 4form wit-h the outer wall plates casings for noush ing `rock wool material serving for sound-proofing-the top end ofthe booth.

Means in the form of 'angle bars lsecured to the cornerv posts serve for securing the top end and the lower disposed cover-like sections'attlieir intersecting'poi-nts in assembled relationto the outer Adisposedrear andthe outer common side wall plates, while reenforcing the corner posts laterally. Y f

`Means lin 'the form of triangular-shaped plates welded to the ledge portions of the side wall plates, the rear wall plate'and the rearlcorner posts reenforce the vbooth framethus constructed againsta `force applied between the corner posts forming'theentrance of the booth. I

Means is provided at the upper `ends lof the outer"dispose`rd wall plates v'for securing a roof and a ceiling, the latter being made of a perforated metallic sheet which in cooperation with the roof plate fori-ns 'a casing for housing brcus material serving 'for sound-proofing ofthe top end of thebooth. Y f

Means carried by the roof `plate ancient-ending downwardly therefrom forms the front side wall and a lwall element at the 'top entrance of 'the booth, wl'1ile means in the form of a rectangular ly-shaped `plate yengaging means carried lby that element cooperates with a rin ofthe ceiling and the roof to form Aa casing forhousinga lighting fixture at the top front' side of the booth, the rectangular plate being secured along its other longitudinaledge to the ceiling ofthe booth.
